Therapeutic Challenges with Catastrophic Antiphospholipid Antibody Syndrome: A Case Report

Abstract

Antiphospholipid antibody syndrome (APS) is a multisystem disorder characterized by thromboembolic events in the presence of antiphospholipid antibodies (APLA). Catastrophic antiphospholipid antibody syndrome (CAPS) is an uncommon variant of APS which is associated with widespread coagulopathy that predominantly affects small vessels. Despite maximal treatment, CAPS has a very high mortality rate. We present a case of a 42-year-old woman with a history of APS who presented to our hospital with complaints of epistaxis, hemoptysis, menorrhagia, and shortness of breath. She was diagnosed with CAPS and developed multiorgan failure and sepsis. Despite maximal treatment with immune modulators, she unfortunately succumbed. With this case, we highlight the importance of early recognition of CAPS and review various treatment modalities that have been proven beneficial. Despite these modalities, CAPS remains a therapeutic challenge in many cases and has a high mortality rate.
